2013-08-26 03:58:55: Created issue 'text-combine-horizontal example 20 is incorrect' nickname owned by John Daggett on product CSS3 Writing Modes, description 'The Writing Modes spec was recently changed to require the use of width variants when they are available for all characters in an affected text run. The spec however still contains wording in example 20 that implies this behavior is optional.
"a simple OpenType-based implementation might compress the text as follows"
"A more sophisticated OpenType implementation might compose the text first with normal (proportional-width) glyphs to see if that fits, then substitute in half-width or third-width forms as available and necessary, possibly adjusting its approach or combining it with scaling operations depending on the available glyph substitutions."' non-public [John Daggett]
